sect-ions 1 to be adjusted nearer to or farther from each other according to the size or diameter of the rope to which the apparatus may be applied. Thus, it will be understood that, by adjustment of the nuts on the bolts 2 and 4, the frame sections may be brought nearer to, or allowed to separate more widely from, each other. Levers 6 and 7 are secured on the inner ends of the frame sections, the joint employed being what is commonly called a knuckle. That is to say, the inner end of each of the frame sections is provided with an integral projection 1 which is rounded and enters a cor responding cavity in the jaws 6 and 7 The clamps or jaws 8 are duplicates, the same being constructed with a tapered longitudinal groove which adapts them to clamp the hemp rope 00 in a most effective manner, as will be understood by reference to Fig. 2. The jaws are supported detachably on the levers, the latter being for this purpose provided with vertical tapered teeth 9 which project through slots or tapered openings in lugs 8 forming integral lateral projections of the jaws. The lower ends of the jaws may be secured to the frame sections 1 by means of machine bolts 10, as

To all whom it may concern Be it known that I, SILAS E. RYDER, a citizen of the United States, and a resident of Muskogee, in the county of Muskogee and State of Oklahoma, have invented an Iniprovement in Rope-Clamps, of which the following is a specification.

My invention is an improvement in that type of rope-clamps whose chief parts are a. frame, jaws 0r clamps proper hinge thereon, and a screw relatively connecting the outer ends of the clamp arms which project laterally from the jaws, so that by rotation of said screw, the jaws may be clamped upon the rope with any required degree of pressure.

The clamp as a whole is adapted for use in various situations, and particularly as an attachment of a well-drilling apparatus.

The apparatus embodies novel features which are hereinafter described in detail and are illustrated in the accompanying drawing, in which Figure 1 is in part a plan or top view and in part a horizontal section of the apparatus on the line 1-1 of Fig. 2. Fig. 2 is a side view of the apparatus including jaws adapted for clamping a hemp rope.

Fig. 2 is a top v1ew of a section of the frame shown in Flg. 2. The angular lateral proand one of the levers for operating the jaws, ections 9 Fig. 5, on the backs of the jaws portions of the frame being shown in horifit in corresponding sockets 9 formed in the levers--see Fig. 2 This construction relieves some of the strain or side pressure that would otherwise be imposed solely on the screws 10. It will now be understood that, by removing the bolts 10, the jaws 8 may be lifted out or detached from the apparatus and others substituted, as occasion requlres.

The outer ends of the toggle levers 6 and 7 may be forced toward each other by means of a link 11, a screw 12, and a pivoted swinging arm 13 which is arranged horizontally directly behind, or outside of, the lever 7 The screw 12 works in a transverse threaded hole in the arm 13 and its inner end enters a shallow groove in the side of the lever 7. A handle 12 of any suitable character is provided for rotating the screw 12. The free end of the link 11 receives the ends of the lever 7 and the arm 13 and engages a groove in the outer side of the latter. It will now be readily understood that by rotating the screw, the arm 13 will be carried toward the handle 12 and the ends of the lovers 6 and 7 will be forced toward each zontal section. Fig. 2 is a plan view of a modified form of link forming part of the apparatus. Fig. 3 is an end view of the ap paratus. Fig. 4- is a side view of clamps or jaws applied to a wire rope. Fig. 5 is a longitudinal section of the jaws shown in Fig. t. Fig. 6 is a plan or top view of these jaws.

As shown in Fig. 1, and in part in Fig. 2 the frame of the apparatus is formed of two like parts 1 and 1 which are curved in form and whose rear or outer ends are rounded on the inner side and adjustably connected by means of a screw-bolt 2. This bolt passes through perforated lugs 3 formed integrally with the bodies of the frame section 1. thus form practically a hinge connection at that point.

The inner ends of the frame sections 1 are adjustably connected by means of a long screw-bolt 4; which passes through lugs 5 cast integrally with the frame sections 1 and having openings which are enlarged and tapered in such a manner as to accommodate the bolt t, or, in other words, to allow the Patented Apr. 21, 1914.

so as to cause the so with the required other correspondingly, jaws 8 to clamp the rope force.

Fig. 2 illustrates a modification of the link, where it is shown constructed as to its body in the form of a clevis and its free ends provided with registering openings adapted to receive a screw-bolt 11 y this construction, the link may or detached from the lever 6.

The inner ends of the levers 6 and 7 are provided with teeth 6 toward each other and the other, as shown in Fig. l, which teeth serve to prevent a zigzag motion or a forward and backward motion of the frame sections and their attachments when the apparatus is being operated.

The apparatus constituting the rope-clamp as described is suspended, in practice, from a temper-screw (not shown) by means of links 14 which are attached to perforated lugs 15 constructed integrally with the frame sections 1 as will be understood by reference to Figs. 2 and 3.

It will be understood that the jaws 8 shown in Figs. l and 5 are the same as those shown in Figs. 1 and 2, save that the grooves in their adjacent inner sides are constructed to receive a wire rope instead of a hemp rope. The central lateral projections 16 are merely ribs strengthening the jaws at that point.

What I claim is 1- 1. A rope-clamp, comprising a frame formed of duplicate sections and means for adjustably connecting them to permit theiradjustment toward or from each other, le-

one working within be readily applied to and 7 which project vers pivoted on such frame sections, jaws supported on the levers, and means for adjusting the latter to clamp a rope, as described.

2. A rope-clamp comprising a frame formed of duplicate curved sect-ions, screw bolts adjustably connecting their outer and inner portions, levers jointed on the inner ends of said sections, jaws carried by the levers and means for adjusting the latter for clamping a rope, as described.

3. In a rope-clamp of the class indicated,

in combination with duplicate frame sec-.

tions having their outer ends constructed with perforated lugs whose contact sides are rounded, a screw bolt passing through said lugs and loosely connecting the ends of the frame sections, the inner ends of said sections having other perforated lugs and an adjusting bolt passing through the latter, levers hinged adjacent to the last-named lugs, rope jaws supported on the levers, and means for adjusting the latter for clamping a rope, as described.

4. A rope-clamp comprising a frame, levers jointed thereto, clamping jaws carried by said levers, an arm pivoted to one side of the frame and extending alongside one of said levers, a link for connecting the opposite lever with said arm, and a screw passing through the arm and bearing against the adjacent lever for adjusting the levers to clamp a rope in the described.
